Why am I bad and inconsistent at online chess compared to OTB
The time control you choose is an obvious factor. Compare what you play OTB with what you play online. Also ask yourself why you play OTB chess and why you play online chess. If there is a difference in your motivation between the two, there is likely a difference in focus in playing the two as well. When you play OTB, how often do you see and play the same people? If you know your opponents style, you are less likely to make mistakes.
So I seem to play so much worse online and make so many mistakes and blunders, on the board I played much better and had a much easier time focusing, please help me, should I uninstall the app, what can I do to sort this out?
